Api5ct casing can be divided into seamless and welded steel tubes, welded steel tube mainly refers to the straight seam steel pipe, large diameter casing is generally straight seam submerged arc-welded steel tubes. Mainly used for transportation of oil, natural gas, coal gas, water and other liquids and gases. The main applications of the product, mainly distributed in the Middle East, Europe and North America. Api5ct according to the length of the casing can be divided into R-1,R-2 and R-3, three kinds of specifications.

Usage:Tube for conveying gas, water, and oil in both and natural gas industries etc.
Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes.

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. The following different types of casing are used in the extraction process:
Surface casing
- Protects the well from contamination in shallow water and gas layers.
- Supports the wellhead equipment and sustains the weight of the other layers of casing.
Intermediate casing
- Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing.
- Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well.
Production casing (oil string)
- It is the conduit through which oil and gas pass from a below surface reservoir.
- It protects the well and separates fluids into various layers.
For the manufacture of casing, green pipes are threaded on each end at first. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. The casing are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into casing.
1.The slotted tube using J55 or N80 oil casing ontology processing, high strength, hard to distortion
